Fixed bug 3985 - SDL_CreateWindow() has stopped changing screen mode when SDL_WINDOW_FULLSCREEN is used
Anthony
This worked in 2.0.5 as normal, but stopped working in 2.0.7. The monitor's resolution doesn't change, a window is created in full screen mode at the virtual desktop resolution instead.

Restored borderless window behavior where DOTA created a borderless window the size of the desktop and expected it to behave like a fullscreen desktop window.
A future SDL release will change the borderless window to act more like a normal window that happens to have no chrome, to support windows that draw their own chrome. In the meantime, those applications should set the "SDL_BORDERLESS_WINDOWED_STYLE" hint.

Fixed bug 4018 - Implement SDL_GetWindowBordersSize() under Windows/Win32/WinAPI
Ismael Ferreras Morezuelas (Swyter)
As a new year gift I have implemented the Windows version of SDL_GetWindowBordersSize(). I needed it for auto-selecting a cozy window size for the game I'm currently working on and noticed that it only worked under X11, so I thought it could be a good excuse to contribute back more stuff. The Mercurial patch is attached as a .diff file. Let me know what you think.
Happy 2018 to all the SDL2 devs and users!
--
PS: Keep in mind that Windows 10 includes the 8px invisible grip borders as part of the frame. There's a way of detecting if Aero/DWM is being used and ask only for the visible rect, but I believe that GetWindowRect() is doing that for a reason and working as intended, so I haven't changed it. (See [2])

metal: Misc. improvements.
- Use a single buffer for various non-changing constants accessed by the GPU, instead of multiple buffers.
- Do the half-pixel offset for points and lines using a transform matrix so we don't need a malloc when rendering.
- Don't add a half-pixel offset for other primitives and textures. This matches D3D and GL render behaviour.
- Remove the half-texel texture coordinate offset since it's not needed now that there's no more half-pixel position offset when rendering a texture.
- Don't try to set texture usage on iOS 8 since it doesn't exist there.

windows: Remove references to GetVersionExA (thanks, Andrew Pilley!).
"GetVersionExA is deprecated in windows 8.1 and above's SDK, causing a warning
when building against the win10 SDK. Attached patch cleans up the usage for a
warning-free build.
GetVersionExA was being used to test to see if SDL was running on win9x or
winnt. A quick chat with Ryan on twitter suggested that SDL doesn't
officially support win9x anymore, so the call to this can be outright removed.
As an aside, replacing the call to GetVersionExA with VerifyVersionInfoA (the
recommended path) would have been pointless, as VerifyVersionInfoA only
supports VER_PLATFORM_WIN32_NT and doesn't officially support any other value
for dwPlatformId currently. (And it's probable that win9x SDKs didn't have
VerifyVersionInfo* in them anyway.)"
Fixes Bugzilla #4019.

Fixed bug 4000 - SDL2 on raspberry: mouse displayed at 0,0 after SDL_ShowCursor
Laurent Merckx
I have a problem with the SDL_ShowCursor method on Raspberry.
Depending on the context, my application hides or show the mouse cursor with SDL_ShowCursor.
But when calling SDL_ShowCursor(true), the cursor is displayed at 0,0 (and not at last position).
After debugging sources by myself, it seems that the problem is in SDL_rpimouse.c - RPI_ShowCursor:
vc_dispmanx_rect_set( &dst_rect, 0, 0, curdata->w, curdata->h);
should be
vc_dispmanx_rect_set( &dst_rect, mouse->x, mouse->y, curdata->w, curdata->h);
For me, it solves the problem.

Dominik Reichardt
As discussed in 2012 the iOS onscreen keyboard hides when you hit RETURN (see https://discourse.libsdl.org/t/on-screen-keyboard-change/19216).
IMO this is a bad idea to not be able to influence this behavior and just recently this was fixed for Android by adding the hint SDL_HINT_ANDROID_RETURN_HIDES_IME in changeset 11768 6ce3bb5e38a5.

Fixed bug 3981 - Inverted logic bug in SDL_renderer "overscan" feature
Eric wing
There is a tiny bug in the new overscan code for the SDL_renderer.
In SDL_renderer.c, line 1265, the if check for SDL_strcasecmp with "direct3d" needs to be inverted.
Instead of:
if(SDL_strcasecmp("direct3d", SDL_GetCurrentVideoDriver())) {
It should be:
if(0 == SDL_strcasecmp("direct3d", SDL_GetCurrentVideoDriver())) {
This bug causes the "overscan" mode to pretty much be completely ignored in all cases and all things remain letterboxed (as before the feature).

Workaround for bug 3931 - spurious SDL_MOUSEMOTION events with SDL_HINT_MOUSE_RELATIVE_MODE_WARP 1 since Windows 10 Fall Creators update
Elis?e Maurer
The attached minimal program sets the SDL_HINT_MOUSE_RELATIVE_MODE_WARP to 1, enables relative mouse mode then logs all SDL_MOUSEMOTION xrel values as they happen.
When moving the mouse exclusively to the right:
* On a Windows 10 installation before Fall Creators update (for instance, Version 10.0.15063 Build 15063), only positive values are reported, as expected
* On a Windows 10 installation after Fall Creators update (for instance, Version 10.0.16299 Update 16299), a mix of positive and negative values are reported.
3 different people have reproduced this bug and have confirmed it started to happen after the Fall Creators update was installed. It happens with SDL 2.0.7 as well as latest default branch as of today.
It seems like some obscure (maybe unintended) Windows behavior change? Haven't been able to pin it down more yet.
(To force-upgrade a Windows installation to the Fall Creators update, you can use the update assistant at https://www.microsoft.com/en-us/software-download/windows10)
Eric Wasylishen
Broken GetCursorPos / SetCursorPos based games on Win 10 fall creators are not limited to SDL.. I just tested winquake.exe (original 1997 exe) and it now has "jumps" in the mouse input if you try to look around in a circle. It uses GetCursorPos/SetCursorPos by default. Switching WinQuake to use directinput (-dinput flag) seems to get rid of the jumps.
Daniel Gibson
A friend tested on Win10 1607 (which is before the Fall Creators Update) and the the bug doesn't occur there, so the regression that SetCursorPos() doesn't reliably generate mouse events was indeed introduced with that update.
I even reproduced it in a minimal WinAPI-only application (https://gist.github.com/DanielGibson/b5b033c67b9137f0280af9fc53352c68), the weird thing is that if you don't do anything each "frame" (i.e. the mainloop only polls the events and does nothing else), there are a lot of mouse events with the coordinates you passed to SetCursorPos(), but when sleeping for 10ms in each iteration of the mainloop, those events basically don't happen anymore. Which is bad, because in games the each iteration of the mainloop usually takes 16ms..
I have a patch now that I find acceptable.
It checks for the windows version with RtlGetVersion() (https://msdn.microsoft.com/en-us/library/windows/hardware/ff561910.aspx) and only if it's >= Win10 build 16299, enables the workaround.
All code is in video/windows/SDL_windowsevents.c
and the workaround is, that for each WM_MOUSEMOVE event, "if(isWin10FCUorNewer && mouseID != SDL_TOUCH_MOUSEID && mouse->relative_mode_warp)", an addition mouse move event is generated with the coordinates of the center of the screen
(SDL_SendMouseMotion(data->window, mouseID, 0, center_x, center_y);) - which is exactly what would happen if windows generated those reliably itself.
This will cause SDL_PrivateSendMouseMotion() to set mouse->last_x = center_x; and mouse->last_y = center_y; so the next mouse relative mouse event will be calculated correctly.
If Microsoft ever fixes this bug, the IsWin10FCUorNewer() function would have to
be adjusted to also check for a maximum version, so the workaround is then disabled again.

Fixed bug 1878 - Scaled texture draws with filtering produce wrapping artifacts.
Yuri K. Schlesner
When using texture filtering, there are filtering artifacts visible on the edges of scaled textures, where the texture filtering pulls in texels from the other side of the texture. Using clamping texture modes wouldn't completely fix this since source rectangles don't need to cover the whole texture. (See screenshot attached in next post.)
The opengl driver uses clamping on textures and so avoid this at least in the cases where the source rect is the whole texture. The direct3d driver does not and so has problems in every case. I'm not sure if it can actually completely be fixed, but at least enabling clamping for direct3d would be one step in the right direction.

This works better for games where there may be a bunch of simulation logic that needs to be run before the next rendering pass, and prevents blocking if the next drawable is busy.

Enable building the Metal renderer by default, and weak link the Metal framework so the SDL library is safe to use on older Macs
Also generate iOS versions of the Metal shaders

audio: Port WASAPI to WinRT, remove XAudio2 backend.
XAudio2 doesn't have capture support, so WASAPI was to replace it; the holdout
was WinRT, which still needed it as its primary audio target until the WASAPI
code code be made to work.
The support matrix now looks like:
WinXP: directsound by default, winmm as a fallback for buggy drivers.
Vista+: WASAPI (directsound and winmm as fallbacks for debugging).
WinRT: WASAPI

Fixed bug 3980 - Fix for KMSDRM driver where cursor would not be shown on some gfx hardware because of unsupported cursor size
Manuel Alfayate Corchete
This fixes a problem with KMSDRM on some graphics hardware where only bigger cursor sizes are supported, such as current Intel gfx. (The kernel-side driver is what limits this: had to look for failing IOCTLs...)
That caused SDL_SetCursor() to fail silently, and we were left with a missing cursor without further explanation.
With this patch, different "standard" sizes are tried and a bigger one is used (with an intermediate and clean buffer only used to write the new cursor to the BO where it will live after) if we get, let's say, 16x16 which is pretty common but our hardware does not support that.
